To all 'whom it may concern:

Be it known that I, .IEssE G. VINCENT, a citizen of the United States, residing at Detroit,Wayne county, Michigan, haveinvented certain new and useful Improvements in Adding-Machines', of which the following is a specification.

' machine may be operated by the act of taking a total or lof clearing the machine without operating said special key.

Inthe present instance, I have shown my invention applied to and incorporated with the well known Burroughs adding machine, constructed and operating substantially as set forth in Letters Patent of the Unitedv States, Nos. 504,963, and 505,078, issued on September 12, 1893, on the invention of William S. Burroughs, but it will be understood that my invention is not limited, in' its application or scope, to this particular type and construction of machine but that it may be applied to and used in connection with other. machines of the same general character and used for the same general.

purposes.

In the drawings, Figure 1 is afront elevation of a Burroughs adding'machinewith my power driven connections applied thereto-in the present instance driven by an electric motor.; Fig. 2 a side elevation of such machine, operating connections and motor, the view) illustrating the left-hand side' of the Burroughs machine and, like Fig. 1, illustratingonly those parts of the machine which are more or less directly concerned with a. proper description and understanding of the features constituting my invention; Fig. 3 a side elevation illustratinlg the driving connections, such view being similar to that of Fig. 2 as to such connections but on a larger scale and with a protecting `casing or guard removed; Fig.`4 a section on the line 4-4 of Fig. 6; Fig.- 5 a perspective of the catches, co-operating with the clutch; Fig; G a section on the line 6--6 of Fig. 3; Fig. 7 a sec-l tion on the line 7-7 of Fig. 6; Fig. S an elevation of the ylocking device for locking the driven .member or the clutch against backward rotation; Fig. 9 a detail view showing certain of'the parts in operated position; Fig. 10 a perspective of the co-operating portions of the baror link 216 and the stem of the operating key; Fig. 1l a detail of anadjusting device for timing the operation of the safety catch,I Fig. 12 a detail view of the bellcrank and pawl concerned with the automatic operation of the special key stem 3522; and Fig. 13 represents the complete machine in left-side elevation with some parts in section.

Inasrnuch as the Burroughs adding machine, to which I have chosen to apply my invention for the purpose of affording a clear -and comprehensive understanding thereof, is well known both as to construction and mode of operation, only-such parts thereof have been illustrated and will be described as are more or less directly concerned with the operating parts or'devices constituting my invention. l

As is well known, the Burroughs adding machineis provided with a keyboard having a series of keys 291 arranged in rows representing'different denominations` increasing from right to left, the keys in 'each row representing the digits 1 to 9. The keyboard is also provided with a total key 265 co-operating with the'mechanism of the machine, whereby a grand total or a sub-total may be printed by the machine at the will of the operator. l The keyboard may also be provided with special keys, such as an error and repeat key, but such keys perform no special function in the operation of the parts constituting my invention.

The operating parts ofthe machine are driven by the main operating shaft 300, which as shown is provided with an operating crank 3568 for operating the machine v by rocking such shaft against spring pressure tending to hold the main shaft in normal position in the usual and well known manner. This crank which in the present instance points forwardly in the normal condition of the machine is operatively connected at its outer end with the driving connections which are operated by a motor-in the present instance, an electric motorin the manner hereinafter described.

As illustrated in Fig. 2, the Burroughs machine is provided with a rock shaft 1400 extending transversely K of the machine and rocked in the act of taking a total or of clearing the machine. As herein shown, this shaft is operatively connected with 'the total key'265, with the result that such shaft is rocked in a clockwise direction .whenever the total key is depressed and is'restored to normal position when the total key is released. The total key is also operatively connected as usual-with a transverse rock shaft 204 which partakes of the same rocking movements as the shaft 1400 inthe operation of the total key. On the right-hand side of the machine, as illustrated in Fig. 2, the shaft 1400 is provided with a depending arni 1411 carrying at I itslower end a lug 1412 which co-operates with a lug 315 on the sector 311. When the total key is depressed,

the depending arm 1411 and its lug 1412 are moved in a clockwise direction and after .the main operating shaft 300 has started in its forward or anti-clockwise movement the total key and its connections are kept in operated condition by the engagement of the lug 315, with the lug 1412,l itbeing understood thatV the sector 311 is secured to and movable with the main. shaft 300. The shaft 1400 is also provided with a crank arm 1410, operatively connected-with a depending arm 227B. byY

means of a link 1416, the arm 227R being secured to the roclshaft 204 and rocked thereby. The lower end of 4the arm 227B. is also pivotally' connected to' a link 216 extending forwardly of the machineand provided with the well known universal rod or bar 209, which coope'rates with the totalizing mechanism of the machine in,

the well known way., l l The bell crank lever 22711 on which the total key or button is mounted has asusual a slot-and-pin connection (see Fig. 13)- with alink 911, the latter being connected with the Usualpitman 914 for regulating the p lan oscillating arm of lever 813 whose movements accompanythatof the operating handle of the machine except thatlthe direction of movement is reversed. The forward end of the pitman is branched for engagement with studs 958-and 958n on one side plate 910L of the rocking frame in which the accumulator is carried.

Normally the upperibranch ofthe pitman engages with the upper stud 958, so that reciprocations of the pitman will move the accumulator pinions first out of and then into engagement with the operating rack 610. When the total key 265 is depressed this upper branch of the pitman is disengaged from the stud 958 so that during the forward stroke of the operating handle the accumulator .pinions remain in mesh with the racksl When the handle is moved rearwardly with said key still depressed the lower branch of the pitman acts against the stud 958 and the accumulator pinions are carried out of engagement with their actuating racks in the usual and well-known manner. If a sub-.total is desired the total key is released before the operating handle starts on its rearward journey withI the result that no actionof the pitman against the stud 958 takes place and the accu? mulator pinions remain in mesh with their actuating racks. The latter are mounted as usual upon the forward ends of the levers 611 independently journaled upona central cross shaft 600 and carrying at their rear ends .sets of type 618, as shown in Fig. -13.

stops set by depression of amount keys in the customary way. When taking a total of course there is no depression of amount keys. The extent oi movement of the racks is then vdetermined by Stops-which limit bade ward rotation of the accumulator pinions to positions where zeros show through the accumulator sight openings. In itemizing operations the individual rack links 216, the latter being connected with the arm 227B. and the bell crank 227L respectively.

The parts above described, with the exception ofthe crank 3568, are those which are usual and well known in a Burroughs machine and are the parts with which the power driven operating connections co-operate, or by'which said connections are controlled. As hereinafter explained these connections are operated by a suitable motor,in the present instance, by a continuously running electric motor-which is permitted to transmit its power thereto by a clutch device under the control of the operator, in themanner hereinafter made apparent.

As illustrated in' Figs. 1, 2 and 3, the base 1165 of the Burroughs machine rests upon the top of a suitable supporting frame or stand composed, as shown, of legs or standards 359% and a topl plate or cross frame 3565, i

which carries or supports the motor and clutch mechananism hereinafter described. The motor A is, in the present instance, an electric motor, of any suitable construction and of a power sufiicient for the purposes. The motor, which, as shown, is suspended from the top plate 3565 of the stand in anydesired manner, is provided with an extended armature shaft 3503, to which is secured a spiral pinion 3596, Figs. 2 and 6. This pinion engages or meshes with a spiral gear'3595, which is loosely 'mounted upon a shaft 3500 extending transv versely of the machine, Fig. 1 and having at its inner end suitable bearings in the extended casing 3566 of themotor and having at its outer end suitable bearings in the lug 3565 depending from the top plate 3565, as shown in Figs. 2, 3 and 6. This gear 3595 forms a part of or is connected with the driving member of a clutch but, describing the present construction, such gear has a laterally extending clutch ring 3538, Figs. 6 and 7, forming a shell which is adapted to receive the driven member of the clutch and whose inner face constitutes a clutch face or surface. present instance, is a disk 3539 which is keyed upon the shaft 3500, but arranged to drive the same when connected with the clutch member or ring 3538 in the mannerhereinafter explained,

As shown in Fig. 7, the-driven member or disk 3539 of the clutch is provided on its margin with a series ol' re-entrant notches 3539, in which are loosely arranged a series oi small rollers 3550 normally forced outwardly vaway from the `Vinner corner of the recesses orv notches with a yielding pressure, as by means of the springs.

3587. When these rollers are positioned inP the corner of the recesses against their spring action, no clutch action exists and the gear 3595 and the driving member or clutch ring 3538 of the clutch operate freely while the driven member or disk 3539 and shaft 3500 are station- This driven member, in the.

ary, it being understood that these rollers when permitted to be pressed outwardly by the springs form thehereinafter described. To this `end, the clutch is provided with a circular plate 3510 having a series of inwardly directed pins 3552; which are receivedv by the notches or recesses 3539 and serve `to normally press the rollers 3550 to inoperative positionagainst the tension of their springs, Figs. 6 and 7. This plate 3510 is .loosely mounted on the shaft 3500 and is provided with I The main catch or latch for the clutch device consists, in the present instance, of a half disk 3501, Fig. 6 and 7, secured at the inner end of a transverse shaft 3501 which has its bearings in suitable manner in the top plate 3565 and in the cap plate 35665 covering the gear case 3566. At a point intermediate its length this shaft is provided with a crank arm 3518 which is spring pressed to the normal position indicated in the drawings by means of a spring` 3582 and is operatively connected with an operating key or button under the control of the operator in the manner hereinafter explained. This shaft 3501 is a rock shaft, and, for the purpose of limitingI the amount of rocking in both directions, the same is provided at its outer end with a limit plate '3520 having a slot 3520, to -co-operate with aiXed pin 3563, projecting from thetop plate 3565, Figs. 2, 3 and 6. .It

will be u'nderstood` that when the crank arm 3518 is rocked in' a clockwise direction, Fig. 7, the catch 3501"L vwhich 4is normally interposed in the path of movement of the arm 3511 and stopped by the left-hand corner of that catch (Fig. 7), will be removed or withdrawn from engagement with the arm 3511, with the result that the pressure ofthe pins 3552 against the rollers 3550 will be removed and such rollers forced to engaging position by their springs, for thelpurpose `of operatively connecting the driving and driven members of the clutch.

The disk 3539 .will thereupon be rotated by theclutch bers of theclutch by reason of the action of the pins 3552 upon the rollers 3550 which are thereby forced toinoperative position against the action of their springs. However, for a purpose hereinafter made apparent, an additional or safety catch is provided which, in the present instance, consists of a pivoted arm 3512 secured to a rock shaft 3502 and terminating at its free end in a hook 3512, arranged in the path of movement of the outer or free en'd of the controlling arm 3511. The arrangement and construction. of the operating connections=is such that after the regular catch 35018' is released, the safetyb catch 3512, moves from its normal or inoperative position in'dicated in Fig. 7 to a position in the path of movement of the arm 3511 and prevents such arm from making more than a single rotation, whatever may bepthe particular-position of the regular catch at the time. The 4relative arrangement ofn these two catches is such' that the safety catch holds the arm 3511 slightly to the left (Fig. 7) of its position when stopped or engaged by the other or regular latch. Consequently, when the safety catch is released in the automatiemanner hereinafter described, the arm 3511 will move a very slight distance before being engaged and retained b'y the regular catch. While the normal position of the safety catch is the inoperative one illus- ,trated irrFig. 7, yet it is pressed with a yielding pressure toward operative position, and to this end I utilize,

in the present instance, the same lspring 3582 which serves to hold the other catch 3501 to its normal position-'of engagement with the arm 3511, as clearly indicated `in Fig 4. As herein shown, the movement of the safety catch to operative position is limited by the contact of a limit arm I3519 against an abutment 3565!), Fig. 4, said limit larm being secured to the shaft 3502 intermediate its length. For thepurpose of securing automatic control of the safety catch, I secure upon the -outer end of its shaft 3502 a controlling arm 3513 which is extended to such a position'fas to be contacted and operated by the connections between the driving s/haft 3500 and the operating crank 3568, as hereinafter eX- planedhFig. 3.

The operating connections between theintermittently driven shaft 3500 and the crank 3568 comprise,

in the present instance, a pitman 3521 pivotally connected at its upper end to the outer end'of the crank 3568 and provided with an elongated longitudinally `extending slot 3521a adapted to receive the laterally projecting pin or stud 3540 carried by the upper or free end of the crank arm 3514, which is secured at its other end to the shaft`350( Tn the present instance, the pitman carries at its upper en'd an adjustable head 3568 having forks directly pivoted to the crank 3568 and arranged to screw upon the pitman to obtain the proper length of the connection between the cranks 3514 and 3568. A lock nut 3554 holds these parts in fixed position. The pitman 3521 is provided near-its lower end with an inwardly extending projection or pin 355212, which is adapted to Contact the arm 3513 'and, when the machine is in normal position, to hold such arm in a slightly elevated position, with'the result that the safety catch will beheld to its inoperative or normal position, as indicated in Fig. 7`. This forms the automatic control of the safety Catch above referred to. v

If desired, means maybe provided for regulating the time when the safety catch will permit the release of the l arm 3511 and this may be conveniently done by varying or adjusting the relative positions or time of co-operation of theI controlling arm 3513 of the safety catch and the contact pin 3563. In the present instance, I accomplish this result by making the pin itself adjustable, to which end, as seen in Figs. 3 and 11, I provide the pin proper with a head 3543 eccentric thereto andiadjustable rotarily in a hole in the pitman 3521. In other words the 'Contact pin is eccentric to the axis on which the head thereof turns, with the result that the position ofthe pin may be adj usted relatively to the controlling v arm 3513 so that the safety catch may be released or re'-v moved from.operative position earlier or later as required or desired.

It will be understood from the foregoing description 4Vthat theengagement andl disengagement of the clutch l .members and the.consequentintermittent rotation of `of theI operator and also under the control of the tot'alia-V A ing and clearing mechanisms, as hereinafter explained. l

the shaft 3500 is under the control of the catch 3501. and

that upon a slight rocking of the 'shaft 3501 which carries the same, the' saidshaft 3500 will be rotated: The

rocking of the shaft 3501 and the lconsequent disengagei ment'of the catch 3501i Iisitself under the direct contrdl Tothis end', a verticalopefrating'rod or key stem 3522 is,

inthe present instance, extended alongthe right-hand side of thel'machine, through its base, and pivotally connected at its Ilower end to the crank arm 3518 hereinbefore described. The upper end of this operating key stemis'iextended'through the keyboard of the machine and terminates in a preferably enlargedoperating i' key or button 3598. It is evident that whenever the operating key 3598is ldepressed by the operator the catch 3501?1 will be disengaged from the arm 3511 and the clutch thereby permitted to rotate the shaft 3500,

\ s wihfhe 'result that the pumas 3521 win sra be drawn Idownwardly .andthe 'mainshaft 300 ofthe machine i rocked Vin an.anti-clockwise'direction (Fig. 2) 'and such 35 f late the machine ina positive manner on theforward4 pitman will be permitted to rise and thereby return to normal position independently of and slower than the shaft 3500, byreason of the pin and slot connection beltween it andthe crank. arm .3514. It, will be under- .stood that the driving lconnections operate simply to rock the shaft 300 on its forward stroke and that such shaft, as well as thecrank arm 3568 and the pitman are returned to .their lnormal position by reason of the spring tension always exertedA on the shaft 300, this return movement being, in the present instance, slower than the latter half of the rotation of the crank arm 3514 and'its shaft 3500. Thus the driving connections operstroke or movement ofthe mainshafty 300 and permit such shaft to return in the manner usual in a Burroughs machine, for instance. As hereinbefore stated, the safety catchis held toin- A operativeposition when the Vpitman is in its normal position, as indicated in lFigs. 2 and 3, but, as will be observed, su'ch safety catch is permitted to be pressed' by its Aspring to operativeposition upon the first movementof the shaft3500 and the pitman 3521 and suchs'afety lcatch will remain in such operativev position ready 'to catch and hold the arm351l against more than a single l revolution until the 'pitman' returnstol its normal posi.

tion., whereupon the safety catch will berocked to inoperative position and the arm 3511 will be caught andl engaged byV the regular catch. 3501-4 The purpose'of the safety catch is to prevent vcontinued rotation of the shaft 3500 in the-event that the adding machine or any of the operating connections should become locked and the pitman should'fail to be returned'to normal position,

the. machine cannot be .operated any,y faster than per- 4mitted by the usual dash-pot and the springs which are operatively connected withthe shaft 300 of a Burroughs machine.

By preference, I provide suitable means for preventing. backward movement `of the shaft 3500, such means comprising, in thepresent instance and as illustrated in Figs. 6 and 8,. a cam plate 3516 secured to such shaft at lits left-hand end (Fig. 6) at a point outside of the gear case 3566,' which cam plate co-operatesw'ith a pivoted detent 3515 in suchY manner as to move in a'clockwise direction when viewed asin Fig. 8, but prevent opposite rotation afterv such shaft has completed a rotation. This detent ispivotedat its upper end to a stud 3557 on ,the side ofthe gear case and is provided at its lower end with an anti-friction roller 3537 which bears against the cam surface or edgeof the cam plate. 'When the sh'aft 3500 is rotatedgthe cam forces the detent outwardly against the tension of its spring 3580 until the abrupt shoulder 3516*? is presented to the roller 3537, whereupon such roller and its detent will snap inwardly lto the position indicated in Fig. 8, at which'time the shaft .3500.hasbeen1rotated once and been caught by the ,safety 'catch hereinbefore referred to. By the provision of this locking mechanism the shaft 3500 is kept from moving backwardly, and continued engaging and disengaging actionor uttering of the clutch is thereby prevented,l

' As-herein'illustrated', I .provide suitable connections with the totalizingfland clearing mechanisms for the purpose of operating the machine by the act of the operator in bringing the totalizing or the clearing Vmechanisms into position for action. In the present instance, this result is obtained by simply depressing the total key and operating .its connections without'manually actuating the operating key or button. Refer-V ring to the construction herein shown, I take advantage of the longitudinal or reciprocating movement of the bar or link 216, which is always moved rearwardly of the machine 'when the -total keyor button is depressed and is permitted-to move forwardly, that is to return to normalposition, when the total key or button is restoredeto ,normal position and I also utilize the swinging movement ofthe depending arm 227B. As

clearly indicated in- Figs. 9v and 10, I pivot upon the shaft'204 a bellcrank 1,3523, on whose forwardly rested arm is' pivotallyv mounted a pawl 3524,"whose free end or* tooth is arranged in proximity to the key stem 3522 and is adaptedto co-operate witha notch 3522 cut in the rearward 'edge thereof. y'lfhis pawl is lnormally spring pressed soas tov be presented to such edge of the operating rod by means of a small spring '3583, fastened at one en d to a stud 3524u `on the tail of the pawl -3524vand atits other end to the upper arm of thelbell-crank. The stud or pin 3524 is extended so as topro'je/ct inwardly of the pawl (Fig. 12) and to bear against the top edge of the-upper. arm of the bell-crank,

limitingthe pivotal movement of such pawl for a reasonI hereinafter explained.l The lower end of the depending arm of the` bell-crank 3524 is provided with an inwardly extendingpin or stud 3523., which is arranged to Icooperatewith theforward edgeof the arm 227B in suchmanneres. to belimited thereby in its rearward movement and to be restored to normal posi v position with its stud 3523a against the arm 227R- as described, with a yielding pressure, as by means of the spring 3584 fastened at vone end to the stud 3525b to contact the lower shoulder or endof sueh'recess, as

indicated in Fig. 2. It is evident that when the total key is depressed and the depending arm 227B thereby rocked rearwardly, that is to the right in Fig. 2, the

spring 3584 will tend to draw the forwardly extending' vided for restraining such operation of the key stem and likewise restraining the downward-movement or rocking of the bell-crank by the spring which, in the described movement of thearm 227B, is simply distended so as to put the belLcrank under tension to rock downwardly whenever permitted to do so by the res lease of the keyr stem. In the present instance, the means for thus momentarily locking or restraining the key stem upon the initial depression of the total key or button and until the latter has about reached the limit of its downward movement, comprise an interference between such stem and the reciprocating link or bar 216. This interference consists of a projection or lug 216 extending outwardly toward the inner sid'e or face of the key stem and normally positioned out of the path of movement of a projection. or lug 35221 extending inwardly from the key stem. i

It is evident ,that' upon the initial movement of the total key the link 216 will be moved longitudinally to have been fully brought into operative position, whereupon the key stem will be forced downwardly with rapidity and willbe restored also with rapidity, the pawl being swung suliciently to the right (Fig. 2) to escape .the lower shoulder in the notch of the stem. It

will be understood that inasmuch as the movement of the pawl 3524 is' limited by the stud 3524u as `to the forward movement of its lower end or tooth, such tooth is compelled to move in the arc of a circle described from the axis of shaft 204 as a center and is thereby enabled tofree itself from the notch 'of the key stem when the bellcrank is sufficiently/.rocked This rapid reciprocationor operation of the key stem takes place just as the total key or button reaches the lower limit of its del pression, at which time the parts of the machine are ready either for the totalizing operation (a subtotal or grand total) or for a clearing operation, it being understood that this operation of the operating key by means of the total key or' button and its connections is the same, in result, as the preliminary depression of the total bntton and the immediate or subsequent manual 0peration or depression of the operating key, but such automatic operation of the machine in taking a total or in clearing thus dispensesl with the double manually depressing the total button and the operating key. j Thus a total may be taken or printed or the machine may be cleared with one hand by simply depress-` ing the total )key or button, instead of using both hands one to depress the total button and the other to depress the operating key.. It will bennderstood that when a.

`sub-total is to be taken or printed the total buttonis permitted to ascend at the end of the downward stroke of the crank arm 3568, while a grand total is taken by keeping the total button depressed through a full movement oi the operating parts of the adding machine.

Th motor and clutch, together with the operating connections are compactly arranged in connection with and supported Vby the stand or frame, on which the adding machine is mounted as clearly indicated in Figs. .1 and 2 and in order to shield'or guard the operating connections'at the lower end of the pitman, I prefer to attach a plate or casing 3569, as indicated in Figs. 1, 2

and 6.

The motor infthe present'instance is an electric motor which may be operated by any available current of electricity, such as that for ordinary incandescent lighting, for which purpose a cable and socket is provided for leading the current to the motor, such current being preferably under the control of a switch at the machine itself, such as the ordinary snap switch 3697 mounted at the frontof the stand or frame and preferably having means for indicating whether the current is turned on -or off, Fig. 2.
